One of the most notable innovations of Okadora is a device called the Cyclone Fin. The Cyclone Fin is attached to the lower part of the shaft and the shaft located in the center of the shell. As the fin rotates, the material undergoing drying is tossed upwards adjacent to the heat-transmitting panel. Then it is pushed against the panel by centrifugal force, like a thin film. During this process, material with a higher water content reaches the panel faster than material with a lower water content. As the water evaporates through heating, the material moves upwards over the heating surface. The up and down cyclic motion continues. As the material covers the heating surface in a thin film state, the surface is fully covered by the material, which means that the heating surface acts equally as a heater and an evaporator. Additionally, the time it takes for the material to reach the heating surface is so fast that heat efficiency is dramatically improved, by up to 4 to 6 times compared with a traditional dryer. Furthermore, the Cyclone Fin was developed so as to enable both slurry and liquid waste to reach the heating surface in a very thin layer.
